3. General description

Grundfos MGE 71-160 are frequency-controlled

permanent-magnet motors for single-phase or

three-phase mains connection. The motors

incorporate a PI controller.

You can connect the motors to a signal from an

external sensor and a setpoint signal enabling

control in closed loop. You can also use the motors

for an open-loop system in which the setpoint signal

is used as a speed control signal.

The motors are intended for machines with a square

torque characteristic, such as ventilators and

centrifugal pumps.

The motors incorporate a control panel which is

available in various versions. See section 9. User

interfaces.

Detailed motor settings are made with the wireless

Grundfos R100 remote control or Grundfos GO.

Furthermore, you can read important operating

parameters via R100 or Grundfos GO.

The motors incorporate a functional module. The

functional module is available in various versions

with different inputs and outputs. See section

7.5 Functional modules.

You can fit the motors with a Grundfos CIM module.

A CIM module is an add-on communication interface

module. The CIM module enables data transmission

between the motor and an external system, for

example a BMS or SCADA system. The CIM module

communicates via fieldbus protocols.

You can connect several MGE motors together via

radio or bus communication to create a multimotor

system.

3.1 Radio communication

This product incorporates a radio module for remote

control which is a class 1 device and which you can

use anywhere in the EU without restrictions.

For use in USA and Canada, see Installation in the

USA and Canada on page 62.

Some variants of the product and products sold in

China and Korea have no radio module.

This product can communicate with Grundfos GO

and other MGE motors of the same type via the

built-in radio module.

3.2 Battery

A Li-ion battery is fitted in the FM 300 functional

module.

The Li-ion battery complies with the Battery Directive

(2006/66/EC). The battery does not contain mercury,

lead and cadmium.

6.5 Outdoor installation

If you install the motor outdoors, provide the motor

with a suitable cover and open the drain holes to

avoid condensation on the electronic components.

See figures 4 and 5.

The cover must be sufficiently large to ensure that

the motor is not exposed to direct sunlight, rain or

snow. Grundfos does not supply covers. We

therefore recommend that you have a cover built for

the specific application. In areas with high humidity,

we recommend that you connect the motor

permanently to the mains supply and activate the

built-in standstill heating function. See section

10.19 ""Standstill heating"".

Fig. 4 Examples of covers (not supplied by

Grundfos)

6.6 Drain holes

If you install the motor in moist surroundings or areas

with high humidity, the bottom drain hole must be

open. The enclosure class of the motor will then be

lower. This helps prevent condensation in the motor

as the motor becomes self-venting, and it allows

water and humid air to escape.

The motor has a plugged drain hole on the drive

side. You can turn the flange 90 ° to both sides or

180 °.

Fig. 5 Drain holes

7. Electrical installation

If the power supply cable is damaged, it must be

replaced by the manufacturer, the manufacturer's

service partner or a similarly qualified person.

The user or the installer is responsible for the

installation of correct earthing and protection

according to local regulations. All operations must be

carried out by a qualified electrician.

7.1 Protection against electric shock,

indirect contact

Protective-earth conductors must always have a

yellow and green (PE) or yellow, green and blue

(PEN) colour marking.

7.1.1 Protection against mains voltage transients

The motor is protected against mains voltage

transients in accordance with EN 61800-3.

7.1.2 Motor protection

The motor requires no external motor protection. The

motor incorporates thermal protection against slow

overloading and blocking.

7.1.3 External switch

We recommend that you connect the motor to an

external switch.

Connect the switch via the terminals 2 (DI1) and 6

(GND). See fig. 10 (FM 100), fig. 11 (FM 200) or fig.

12 (FM 300).

Enable the ""External stop"" function. See section

10.7 "Digital inputs".

When fitting a cover to the motor, observe

the guideline in section 6.4 Ensuring motor

cooling.

7.3.2 Three-phase supply voltage

• 3 x 380-500 V - 10 %/+ 10 %, 50/60 Hz, PE.

Check that the supply voltage and frequency

correspond to the values stated on the nameplate.

The wires in the motor terminal box must be as short

as possible. Excepted from this is the separated

earth conductor which must be so long that it is the

last one to be disconnected in case the cable is

inadvertently pulled out of the cable entry.

In order to avoid loose connections, ensure that the

terminal block for L1, L2 and L3 is pressed home in

its socket when the supply cable has been

connected.

For maximum backup fuse, see section 23.1 Supply

voltage.

Fig. 8 Example of a mains-connected

three-phase motor with mains switch,

backup fuses and additional protection

Fig. 9 Mains connection, three-phase motors

7.4 Additional protection

The residual-current circuit breaker must be marked

with the following symbol:

The total leakage current of all the electrical

equipment in the installation must be taken into

account. You find the leakage current of the motor in

section 23.2 Leakage current (AC).

This product can cause a direct current in the

protective earth conductor.

Overvoltage and undervoltage protection

Overvoltage and undervoltage may occur in case of

unstable power supply or a faulty installation. The

motor is stopped if the voltage falls outside the

permissible voltage range. The motor restarts

automatically when the voltage is again within the

permissible voltage range. Therefore, no additional

protection relay is required.

If you want to supply the motor through an

IT network, make sure that you have a

suitable motor variant. If you are in doubt,

contact Grundfos.

Corner earthing is not allowed for supply

voltages above 3 x 480 V, 50/60 Hz.

61800-3. In areas with high lightning

intensity, we recommend external lightning

protection.

English (GB)

11

Overload protection

If the upper load limit is exceeded, the motor

automatically compensates for this by reducing the

speed and stops if the overload condition persists.

The motor remains stopped for a set period. After

this period, the motor automatically attempts to

restart. The overload protection prevents damage to

the motor. Consequently, no additional motor

protection is required.

Overtemperature protection

The electronic unit has a built-in temperature sensor

as an additional protection. When the temperature

rises above a certain level, the motor automatically

compensates for this by reducing the speed and

stops if the temperature keeps rising. The motor

remains stopped for a set period. After this period,

the motor automatically attempts to restart.

Protection against phase unbalance

Connect three-phase motors to a power supply with

a quality corresponding to IEC 60146-1-1, class C, to

ensure correct motor operation at phase unbalance.

This also ensures long life of the components.

7.5 Functional modules

Various functional modules are available:

• basic functional module, FM 100

• standard functional module, FM 200

• advanced functional module, FM 300.

The selection of module depends on the application

and the required number of inputs and outputs.

7.6 Connection terminals on functional

modules

The descriptions and terminal overviews in this

section apply to both single- and three-phase

motors.

For maximum tightening torques, see section

Torques, page 60.

7.6.1 Basic functional module, FM 100

The module has only the most necessary inputs for

closed- and open-loop operation. The module also

enables communication via a GENIbus connection.

The module has these connections:

• analog voltage input

• two digital inputs or one digital input and one

open-collector output

• GENIbus connection.

See fig. 10.

• Inputs and output

The inputs and output are internally separated from

the mains-conducting parts by reinforced insulation

and galvanically separated from other circuits. All

control terminals are supplied by protective extra-low

voltage (PELV), thus ensuring protection against

electric shock.

• Mains supply (terminals N, PE, L or L1, L2, L3,

PE).

Digital input 1 is factory-set to be start/stop

input where open circuit results in stop. A

jumper has been factory-fitted between

terminals 2 and 6. Remove the jumper if

digital input 1 is to be used as external

start/stop or any other external function.

DANGER

Electric shock

- Death or serious personal injury

- Make sure that the wires to be

connected to the connection groups

below are separated from each other by

reinforced insulation in their entire

lengths.

English (GB)

* If you use an external supply source, there must

be a connection to earth.

Fig. 10 Connection terminals, FM 100

7.6.2 Standard functional module, FM 200

The module has more inputs and outputs than FM

100 and is suitable for even more demanding

applications.

The module has these connections:

• two analog inputs

• two digital inputs or one digital input and one

8. Operating conditions

8.1 Maximum number of starts and stops

The number of starts and stops via the power supply

must not exceed four times per hour.

When switched on via the power supply, the motor

starts after approximately 5 seconds.

If a higher number of starts and stops is desired, use

the input for external start/stop when

starting/stopping the motor.

When started via an external on/off switch, the motor

starts immediately.

8.2 Ambient temperature

8.2.1 Ambient temperature during storage and

transportation

Minimum: -30 °C

Maximum: 60 °C.

8.2.2 Ambient temperature during operation

Minimum: -20 °C

Maximum: 50 °C.

The motor can operate with the rated power output

(P2) at 50 °C, but continuous operation at higher

temperatures reduces the expected product life. If

the motor is to operate at ambient temperatures

between 50 and 60 °C, select an oversized motor.

Contact Grundfos for further information.

8.3 Installation altitude

Installation altitude is the height above sea level of

the installation site.

Motors installed up to 1000 metres above sea level

can be loaded 100 %.

Motors installed more than 1000 metres above sea

level must not be fully loaded due to the low density

and consequent low cooling effect of the air. See fig.

16.

Fig. 16 Derating of motor output power (P2) in

relation to altitude above sea level

8.4 Humidity

Maximum humidity: 95 %.

If the humidity is constantly high and above 85 %,

open the drain holes in the drive-end flange. See

section 6.6 Drain holes.

8.5 Motor cooling

To ensure cooling of motor and electronics, observe

the following:

• Position the motor in such a way that adequate

cooling is ensured. See section 6.4 Ensuring

motor cooling.

• The temperature of the cooling air must not

exceed 50 °C.

• Keep cooling fins and fan blades clean.

If the motor is installed above 2000 m, it

does not comply with the SELV/PELV

classification.
